Abstract

Systems and methods related to the field of cardiac resuscitation, and in particular to devices for assisting rescuers in performing cardio-pulmonary resuscitation (CPR) are described herein. A method for managing cardiopulmonary resuscitation (CPR) treatment to a person in need of emergency assistance includes monitoring, with an electronic medical device, a parameter that indicates a quality level of a CPR component being provided to the person by a user; determining, with the electronic medical device, that the parameter indicates that the quality level of CPR being provided is inadequate; and providing, to one or more rescuers of the person, an audible, visual, or tactile indication that a different person should perform the CPR component.

What is claimed is: 
     
       1. A system for managing cardiopulmonary resuscitation (CPR) treatment to a person in need of emergency assistance, the system comprising:
 a chest compression assembly configured to be placed on a chest of the person in need of emergency assistance, the chest compression assembly comprising:
 a housing upon which a rescuer places his/her hands to provide CPR to the person in need of emergency assistance; 
 one or more sensors positioned within the housing and adapted to measure information indicative of CPR being provided to the person in need of emergency assistance; 
 a sensor interface configured to receive input from one or more sensors adapted to measure information indicative of CPR being provided to the person in need of emergency assistance; and 
 a haptic vibrator positioned within the housing and configured to generate a pattern of haptic feedback for the rescuer while the chest compression assembly is being placed on the chest; and 
 
 a processing circuitry operatively coupled with the sensor interface and in communication with the haptic vibrator, the processing circuitry configured to:
 receive input from the one or more sensors, 
 generate an indication of quality of the CPR being provided to the person in need of emergency assistance based the input from the one or more sensors, 
 determine whether the indication of quality of the CPR falls within an acceptable range based on one or more target CPR parameters, and 
 generate the pattern of haptic feedback with the haptic vibrator when the indication of quality of the CPR falls outside of the acceptable range as a prompt to switch the rescuer with another rescuer performing CPR. 
 
 
     
     
       2. The system of  claim 1 , further comprising an output interface that is configured to generate at least one of audible feedback and visual feedback based on the indication of the quality of the CPR. 
     
     
       3. The system of  claim 1 , wherein the sensor interface is configured to receive input from an accelerometer. 
     
     
       4. The system of  claim 1 , wherein the one or more target CPR parameters include at least one of a chest compression parameter and a ventilation parameter. 
     
     
       5. The system of  claim 4 , wherein the chest compression parameter is based on at least one of chest compression depth and chest compression rate. 
     
     
       6. The system of  claim 1 , wherein the indication of quality of the CPR includes a quality score of the CPR administered to the person in need of emergency assistance. 
     
     
       7. The system of  claim 6 , wherein the indication of quality of the CPR includes a determination of whether the quality score falls within the acceptable range based on the one or more target CPR parameters. 
     
     
       8. The system of  claim 6 , wherein the quality score is indicative of an instantaneous quality of CPR administered to the person in need of emergency assistance. 
     
     
       9. The system of  claim 6 , wherein the quality score is indicative of an average quality of CPR administered to the person in need of emergency assistance. 
     
     
       10. The system of  claim 1 , further comprising defibrillation electrodes coupled to the chest compression assembly. 
     
     
       11. The system of  claim 10 , wherein the defibrillation electrodes and the chest compression assembly are coupled together via a wiring harness. 
     
     
       12. The system of  claim 10 , wherein the defibrillation electrodes and the chest compression assembly are adapted to be operatively connected with a defibrillator. 
     
     
       13. The system of  claim 12 , wherein the defibrillation electrodes and the chest compression assembly are adapted to be operatively connected with the defibrillator via a wire. 
     
     
       14. The system of  claim 1 , wherein the haptic vibrator is arranged so as to rest adjacent the rescuer's hands during performance of CPR chest compressions. 
     
     
       15. The system of  claim 1 , wherein the one or more sensors include at least one accelerometer. 
     
     
       16. The system of  claim 1 , wherein a lower side of the housing comprises an adhesive configured to adhere to the chest of the person in need of emergency assistance, thereby coupling the chest compression assembly to the chest of the person in need of emergency assistance. 
     
     
       17. The system of  claim 1 , wherein a continuous vibration provided as the pattern of haptic feedback provides the prompt to switch the rescuer with the other rescuer performing CPR. 
     
     
       18. The system of  claim 1 , wherein the pattern of haptic feedback is provided to guide the rescuer in performing CPR. 
     
     
       19. The system of  claim 1 , wherein the indication of quality of the CPR is based on a calculation of an indication of the rescuer's fatigue. 
     
     
       20. The system of  claim 19 , wherein the indication of the rescuer's fatigue is based at least in part on at least one of chest compression depth and chest compression rate. 
     
     
       21. The system of  claim 1 , further comprising a memory operatively connected to the processing circuitry and configured to store a plurality of signals providing prompts related to CPR. 
     
     
       22. The system of  claim 21 , wherein the prompt to switch the rescuer with the other rescuer performing CPR is selected from the plurality of signals providing prompts related to CPR stored in the memory. 
     
     
       23. The system of  claim 21 , wherein the plurality of signals providing prompts related to CPR stored in memory comprise a prompt related to rate of compressions, a prompt related to depth of compressions, prompts related to an ECG waveform, prompts related to a CO 2  waveform, a perfusion performance indicator, the prompt to switch the rescuer with the other rescuer performing CPR, or any combination thereof.
